Abstract
The invention discloses an automatic-positioning vibration sampler. The automatic-positioning vibration sampler comprises an upper fixing plate, a lower fixing plate, a support plate which is used for connection fixing and is perpendicular to the upper fixing plate and the lower fixing plate, a X-direction driving mechanism arranged on the lower fixing plate, a Y-direction driving mechanism connected to the X-direction driving mechanism, a Z-direction driving mechanism connected to the Y-direction driving mechanism by a longitudinal fixing base and a sampling pin connected to the Z-direction driving mechanism. The automatic-positioning vibration sampler also comprises a sampling pin vibrating mechanism. The sampling pin vibrating mechanism comprises a vibrating motor fixed to the longitudinal fixing base, an eccentric wheel device connected to an output end of the vibrating motor and a vibrating plate connected to the eccentric wheel device by a connection member. One end of the sampling pin goes through the vibrating plate. The eccentric wheel device in the sampling pin vibrating mechanism drives the vibrating plate to carry out eccentric motion so that the sampling pin is further driven to carry out eccentric motion to stir a liquid to be detected in a test tube and thus compared with the existing sampler, the automatic-positioning vibration sampler improves stirring effects and a sampling precision.
